 <div class="section"><h2 class="sectiontitle">Syntax</h2> 
<pre>template&lt;typename InputIterator, typename Func&gt; 
void parallel_for_each (InputIterator first, InputIterator last, 
                        const Func&amp; f

 <div class="section"><h2 class="sectiontitle">Description</h2> <p>A <samp class="codeph">parallel_for_each(<em>first,last,f</em>)</samp>applies<samp class="codeph"><em> f </em></samp>to
    the result of dereferencing every iterator in the range [<em>first,last</em>), possibly in
    parallel. It is provided for PPL compatibility and equivalent to
      <samp class="codeph">parallel_do(<em>first,last,f</em>)</samp> without "feeder" functionality.</p>
<p>If the <samp class="codeph">group</samp> argument is specified, the algorithm's tasks are executed in this
    group. By default the algorithm is executed in a bound group of its own.</p>
